T 0 'aU ill/10m it "my concern.

Be it known that we. (mm-men F. Morel: and KARL J. Moron. citizens of the llnited States, residing at luehlo. in the county of Pueblo and State of Colorado. have invented certain new and useful improvements in Dirigiblc Spot-lights for r tutomohiles, of which the following is u specification.

This invention relates to dirig'ilile spot lights for automobiles, and main object is to provide in connection with an electric headlight mounted in front oi an automobile. a simple and eliicient mechanism for turning: it in conjunction with the steering gear of the some.

Another object of the invention is to provide in connection with :1 headlight of. the character an automatic switch which normally opens the circuit of the lamp and closes the same only. when the steering gear is operated to turn the vehicle in either direction from't-he straight course.

Still other objects of the invention reside in details of construction all of which will be fully described with reference to the accompanying drawings in which like characters of reference designate corresponding parts throughout the several views.

In the drawings Figure 1 represents a front view of a motor vehicle to which our invention is applied;

Figui'e 2, an enlarged sectional elevation on theline 2-2, Figure 1;

Figure 2.3, an enlarged section taken on the line 3-3, Figure 2, and

Figure 4, a fragmentary frontview of the lamp supporting rod of the invention, and adjacent parts of the motor vehicle to which it is applied. I

Referring in detail to the drawings the reference numeral 5 designates a motor vehicle'in which are included the radiator 6, the front or steering wheels 7 mounted. at opposite ends of an axle'8, and a connecting rod 9 which is pivotally connected at its.

onds to the knuckle arms of the steering ear.

All of the parts so for mentioned are of Wellhnown construction and arrangement. Our invention comprises a head lamp 10 of the type commonly known as spot lights which is supported upon a rod 12. The lam is mounted in front of the radiator of t e vehicle by means of a hearing 13 through which its rod extends. The. hearing is rigidly secured to the radiator by bolts or other suitable means and the rod is provided with a collar 14 which rests upon. the

the connectin rod 0! the steering ear of the vehicle for the movable support oi a. forked post 20 of the movement transmitting mechanism lay which the longitudinal movements of the connecting rod are converted into a rotary movement of the lamp support ing rot. in the hearing 13.

The post is superimposed upon return table 21 fitted in ii recess of the clamp block and held against upward movement by acover plate 22 which is fastened upon the bloek by the same bolts which connect its sections.

A sleeve .23 pivotiilly mounted in the fork.

at the upper end of the post provides a' slide-bearing for a crank rod 24 which'has a forked head-for its connection with the lower end of the lam supporting rod 12.

The two ro s are pivotally connected b means of a bolt 28 to permit'of vertical n justment of the lamp. The turn-table of the post provides a convenient medium for controlling the circuit of the spot light which as usual is equipped with an incandescent lamp, the object of this circuit control being to connect the lamp of the spot light in the circuit only when by movement of the steering gear the vehicle is turned in either direction from a straight'oourse.

Theclamp block carries with this object in view an insulated binding shrew 25 which is connected with the lamp of the spot light by a conductor 26 and the turn table has in its circumferential edge on inlsid segment 27 of nonconductinr, material which contacts with the end ofthe screw when the steering gear is in its central position. The conductive part of the turn table is connected in the ground side of the circuit By its electrical connection with the metal con nccting rod of the steering mechanism of the vehicle. From the above description taken in connection with the drawings, it will he understood that whenfthe vehicle to which our invention is applied '15 moving in a straight course, the spot light mounted in front of the automobile faces forwardly with its incandescent lamp in an unlighted positlon.

When for thepurpose of turning the vehicle in either direction from the given course, the connecting rod of the steering gear is moved longitudinally, the consequent movement of the clamp block will cause the crank nod 24. to turn with the post 20 and at the. same time slide lengthwise in the sleeve 23. I

As a result of this movement the spot light is compelled to, turn in its bearings in the same direction in which the vehicle is being moved and its lamp is simultaneously lighted by the contact of the conductive portion of the circumferential edge of the turn table with the end oi": the binding screw.

The spotlight thus illuminates the road at the side of the vehicle in the direction in which the latter is being turned, while the ordinary headlight illuminates the other part of the road, as before.

Having thus described the dirigible spot l-rarer light construction in the most convenient and practical form at present known to us, it will be understood that it is susceptible to changes in the construction and arrangement of, its parts without departing from the principle of the invention.

What we claim and desire to secure by Letters-Patent is:

A dirigible spot light for motor-vehicles comprising an electric head lamp, a supporting rod for the lamp, a bearing for the rod, adapted for connectionto the vehicle, a block adapted for rigid connection with the connecting rod of the steering gearof the vehicle, a turn table on the block, having a peripheral non-conducting segment, an 'insulated binding screw on the block engaging the periphery of the turn table and electrically connected with the lamp, a post on the turn table, and amovement transmitting member between the, post and the lamp-sup- J porting rod.

.In testimony whereof we have ailixed our signatures.
